- Unlock iPhone 4 / 4S On iOS 5.0 / 5.0.1 / 5.1 On Any Baseband With SAM
- Unlock iPhone 4 Baseband 4.11.08 And Baseband 4.12.01 On iOS 5.1 With Gevey Ultra
The post below is old. Above links are fresh with solution available.
The post is written specially for those who are struck on baseband 4.11.08 and are unable to unlock their iPhone 4 device.
Apple introduced a new baseband 4.11.08 along with their latest firmware iOS 5. We do not want to sound too technical by explaining what actually a baseband is. It involves theories of signal and systems and frequencies. All you need to know is that it has everything to do with the unlock of your device.
Anyways coming back to the point. Its a little harsh way to say but truth must be told. Those of you who are struck on iPhone 4 baseband 4.11.08, there is currently no unlock solution. Niether using Ultrasn0w, nor using Gevey Sim.
There are currently two solutions to unlock your device. One is Gevey Sim and the other is Ultrasn0w.
Ultrasn0w, a software unlock for iPhone by iPhone Dev Team. It can unlock iPhone 4 on baseband 01.59.00 and iPhone 3GS on 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00.
Gevey is a sim based unlock solution for iPhone for. It can unlock iPhone 4 with basebands 02.10.04 / 03.10.01 / 04.10.01 and iPhone 3GS with 05.14.02 / 05.15.04 / 05.15.04 / 05.16.01 / 05.16.02.
If you see in the above list of basebands, 4.11.08 is not present because it currently has no unlock. Remember you cannot downgrade your baseband by downgrading your firmware.
The only way a person can have 4.11.08 baseband running iOS 5 and that too with an unlocked device is to have a factory unlocked iPhone. Factory unlocked are contract free devices bought from Apple by paying them additional fee to use it on any carrier network. Just like the one we have :)
For those who have not yet upgraded to iOS 5, we have already posted a guide when it was released. The following link will show you how to preserve your baseband while updating to iOS 5 and you will not end up loosing your unlock

A lot of less technical users and those who are new to unlocking and jailbreaking are unable to get the concept and they end up loosing their money by paying to the fake sites on the Internet.

If any developer comes with some solution to unlock 4.11.08, we will update it on our site as well we will update this post.
